Burps and Peezzzzzz
My son thinks farts are the same thing as burping. So, if he farts or anybody else farts, this tiny high pitched little voice, says, quietly, "burps". I think he says this in lieu of saying, excuse me. He has mastered one polite "good manners" type word. He says "peezzzzz" for please. Burps and Peezzzzz. Mommy's so proud of you!
